In 1982, materials scientist Dan Shechtman observed an unusual tenfold symmetry in an aluminum-manganese alloy, defying the ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

Strain engineering, which involves deliberately stretching or compressing a crystal lattice, is used to boost the speed of electron flow in a device. Even a fraction of percent change in lattice ...

In a process analogous to how solids melt into liquids, the electrons in many different metals form crystal-like patterns ...

When a laser beam is incident on many small objects such as lycopodium powder, the resulting diffraction pattern is similar to the diffraction pattern of a small circular aperture (Airy's disk pattern ...

The (relatively) ancient art of crystallography has had a huge impact on modern science by showing us the location of atoms within a molecule. The structure of DNA (and how it acts as an information ...

Description: Electron diffraction patterns for single crystal and polycrystalline materials are displayed on a CRT screen. A Welch model 2639 'Electron Diffraction tube' is used in an experiment in ...

Nobody knows what the surface of neutron stars are made of but there’s no shortage of suggestions. We know that iron must play a role because we can see its characteristics absorption lines in the ...

What happens when a wave passes through some opening? It diffracts - or you like, you could say "bends". If the size of the opening is comparable to the wavelength of the wave, the bending can be ...
